The exact day of conception: how to find out. Video
The development of pregnancy begins with the fertilization of an egg with a sperm. The day of their merger is considered the date of conception of the unborn child. There are various methods for calculating the date of possible fertilization, all of which are based on determining the day of ovulation – the moment of maturation of the egg.
The exact day of conception: how to find out
Favorable days for conceiving a child
It is believed that a woman can only become pregnant during ovulation. At this time, the fertilized egg is released from the ovary into the uterine cavity. She lives no more than 48 hours, so a couple may not have much time to conceive a child during one menstrual cycle.
Male sperm, once in the vagina, can live for about seven days at best. Therefore, conception is possible only a few days before ovulation, as well as on the day the egg is released into the uterine cavity.
How to find out the exact date of conception
To find out when conception occurred, you need to find out the date of ovulation and compare it with the day when unprotected intercourse occurred.
To calculate the exact day of fertilization, you can use a special calculator by finding it on sites about pregnancy and childbirth, but this is easy to do on your own.
If a woman monitored her ovulation, it is very easy to determine the exact date of conception. This will be the day on which the closest sexual intercourse to this date occurred.
Calculation of the date of ovulation is possible by measuring the basal body temperature, using ultrasound, blood tests for hormones, using diagnostic rapid tests to establish ovulation.
On the basal temperature chart, the day of ovulation is the moment when the line of the measured indicator moves to a higher level (temperature rise by 0,3-0,5 degrees)
If a woman has not followed the onset of ovulation, it will be somewhat more difficult to establish the exact date of conception. The egg, ready for fertilization, leaves the ovary around the middle of the menstrual cycle. The duration of the period between the onset of menstruation is not the same for different women and can range from 24 to 40 days, so both early and late ovulation are possible. In most cases, it happens 14 days before the date of the expected period.
When going to the antenatal clinic, the doctor informs the woman about the gestational age. You can find out it (if the date of the beginning of the last menstruation and the moment of the onset of ovulation are unknown) according to the results of a gynecological examination or ultrasound data. According to the established deadline, it is possible to calculate the date of the expected birth. According to these data, using a special formula, you can find out on what day the conception took place. From the date of birth, you need to count the week and add three months and two weeks to the resulting number. Fertilization most likely occurred on the day received. However, it should be borne in mind that this result is approximate.
